Hello @Vladislav0 and @Maria-Lurdes0,
I am a Chinese, I travel a lot with airbnb and I host my two apartments in Beijing, China.
I do agree that most of the Chinese do not leave the apartment in good condition. Same thing also happen to guests from other parts of east/southeast Asia. It's really annoying that I hosted guests from South Korean and left my apartment in terrible condition. I wrote to them and they replied they didn't know they need to clean it, as they always left the room messy in hotels...
So, I normally reject inquiries from China, east/southeast Asia to avoid this happen again. I only accept guests from these part of the world with positive reviews and overseas living experiences. I seriously inform them when they check in that it is my home, not a hotel, and they should leave it clean, and I posted lots of rules, making all of the price clear if they break the rules. If it really happened, I would definitely leave a negative review and ask them to pay for what they had done. I don't want any other hosts come across this situation again.
I don't want to be racist, but it really happens. The percentage that I prove the booking enquiry from them was much lower than the other parts of the world. That's how I deal with it.
Hope it works.
Happy New Year!
Raymond
